BACKGROUND Patients with hip osteoarthritis (OA) have muscular weakness, impaired balance, and limp. Deficits in the different limb muscles and their recovery courses are largely unknown, however. We hypothesized that there is persisting muscular weakness in lower limb muscles and an impaired balance and gait 2 years after THA. PATIENTS AND METHODS 20 elderly patients with unilateral OA were ...
BACKGROUND The current study focuses on the comparison of postoperative muscular strength around the hip joint of patients with femoral intertrochanteric fractures treated either by cephalo-medullary (CM) nailing or a new bipolar hip prosthesis (BHP), an especially attached device to secure displaced greater trochanteric fragment. METHODS Twenty patients treated with CM nailing were age- and ...
The aim of the present study was to evaluate the use MRI to quantify the workload of gluteus medius (GM), vastus medialis (VM) and vastus lateralis (VL) muscles in different types of squat exercises. Fourteen female volunteers were evaluated, average age of 22 ± 2 years, sedentary, without clinical symptoms, and without history of previous lower limb injuries. Quantitative MRI was used to analy...
BACKGROUND The literature is inconsistent and inconclusive on the relationship between bone mineral density (BMD) and muscular strength in postmenopausal women. OBJECTIVE To evaluate the relationship between isokinetically and isometrically determined muscle strength and BMD in postmenopausal women of different age groups. METHODS Healthy postmenopausal women (n = 293; mean age, 54.22 ± 3.8...
Background: The aim of this study was to investigate muscle damage indicators and electromyography activities of quadriceps muscles at 25° of hip flexion in untrained healthy females after an eccentric exercise induced muscle fiber damage. Methods : A total of 14 healthy females participated in this pre-experimental study. The subjects performed maximal eccentric quadriceps contractions at ...
Background Female patients are more likely to suffer a second anterior cruciate ligament (ACL) injury after ACL reconstruction (ACLR) and return to sport (RTS) compared with healthy female controls. Few studies have examined the energy absorption contribution (EAC) that could lead to this subsequent injury. Hypothesis The ACLR group would demonstrate an altered EAC between joints (hip, knee, ...
BACKGROUND The relationships between hip abductor and extensor strength and frontal plane hip and knee motions that are associated with anterior cruciate ligament injury risk are equivocal. However, previous research on these relationships has evaluated relatively low-level movement tasks and peak torque rather than a time-critical strength measure such as the rate of torque development (RTD). ...
Background and purpose: Strengthening the cervical extensor muscles is recommended as a way of prevention and treatment of neck pain. The purpose of this study was to investigate the effect of two different exercise protocols on isometric strength of the head and neck extensor muscles in healthy subjects. Material and Methods: In this study, a total of twenty-eight healthy females, 20-25 yea...
